Butterflyfish depend on food and shelter provided by coral reefs, but they steer clear of those that have come in contact with seaweed. Researchers suggest this may be a strong indicator of their awareness of reef health.
Genome sequencing, paired with a behavioral test, identified several genes linked to anxiety in chickens. Researchers believe the same genes may play a role in mouse and human behavior.
Vultures are not good at flapping their wings, but they manage to spend long periods of time in the air by soaring. Researchers found that these birds stay aloft by making use of small-scale turbulence that produces uplift without flapping their wings.
Humpback whales are spending some extra time up north in Alaska this season. Experts say the whales are slow to arrive at breeding grounds in Hawaii because of possible food competition or El Niño disruptions.
Although colonies of Florida carpenter ants have designated roles, researchers managed to turn foraging ants into scouts with the use of epigenetic drugs. This suggests social behavior is not necessarily based on an individual's genetics.
Although pitch perception was thought to be unique among humans, researchers recently discovered small monkeys known as marmosets use auditory cues to distinguish between low and high notes, just like we do.
Dogs can rapidly mimic each other's expressions, just like humans and some primates.
Regular, gentle pats and positive human interactions benefit growing calves. This could be advantageous for farmers, as cows produce more milk if they gain more weight at a young age.
Contact, rather than waterborne chemical signals, induces sex change in marine snails known as slipper limpets.
New Caledonian crows were caught on camera for the first time making innovative hook foraging tools in the wild.
Some insect larvae can twitch and whip inside their cocoons in order to "jump" to shadier, or more favorable, environments. Researchers say this is a unique survival technique only seen in select wasp species.
Japanese macaques are exposed to various stressful situations in the wild, including rank fights and mating competitions. Researchers recently took a closer look at how genetics ultimately control the release of stress hormones in these animals.
Fossils of a 508 million-year-old shrimp-like creature known as "Waptia" were discovered in China carrying several eggs with embryos. This find represents the earliest known evidence of brood care, researchers say.
An extinct group of marine reptiles known as plesiosaurs had a very unique body structure. New computer simulations suggest the animals likely used it to move through the water like a penguins.
